MICHAEL, OF ELMAHURST,ILLINOIS?, ASSIGNOE 0F ONE-HALF T0 THE BALDWIN LOCOMOTIVE WORKS, OFPHILADELPHIA, PEHNSYLVANUm A CORPORA- @ION OF PENNSYLVANIA LOCOMOTI'VECONSTRUCTION .Application filed May 3, 1929. Serial No. 360,193.

My invention relates to .railway rolling stock and particularly totheconstruction of cylinder and boiler saddle structure of a locomotive andthe combination therewith of a smoke-box mounted on the saddle and afeed Water heater contained in the smoke-box.

t is customary to provide pipes leading from the steam valve chambersand mounted on the outside of the smoke-box and extending through theWall of the latter to a feed water heater carried in the upper portionof the smoke-box.

The main obj ect of my invention is to eliminate a substantial part ofthis piping and to simplifythe construction and reduce the labor ofassembling thepiping and other structure and also to reduce thelikelihood of undesirable leakage of air into the smoke-box due to thepresence of joints where the piping would ordinarily extend throu h thesmoke-box wall. I attain this object gy providing an exhaust steampassage, in addition to the main exhaust steam passage, in the saddlestructure itself and having a discharge opening in the web plate of thesaddle which supports the boiler, this opening leading to the interiorof the smoke-box.

@ther more detailed objects of my invention and the means for attainingthe same will be apparent :from the detailed description of my inventionand from the accompanying drawings in which- Figure 1 is in part a topView and in part a horizontal section taken on the line 1-1 of Figure 2.n

Figure 2 is a vertical -transverse section taken on the line 2-2 ofFigure 1.

Figure 3 is a side elevation of the saddle and feed water heatermembers, the adjacent portion of the smoke-box being shown in brokenlines. y

Figure 4 is a vertical longitudinal section taken on the line 4-4 ofFigure 1.

Figure 5 is a vertical transverse section taken on the line 5-'5 ofFigure 3.

Figure 6 is a vertical longitudinal section taken on the line 6 6 ofFigure 1.

Figure 7 is a detail horizontal section taken on the line 7--7 ofFigure'2.

Preferably, although .not necessarily, my

saddle structure is formed in one piece and is integral with thelocomotive bed or `forward framing members 1. l illustrate a portion ofthe bed of box-shaped cross section and having the steam cylinders 2 andthe steam valve Y chambers 3 formed integrally therewith. The cylindersand valve chambers on oppomain exhaust steam passages 7 7 which leadfrom the ends of each steam chamber 3 transversely and longitudinallyand upwardly of the saddle through the center of the web plate 5 wherethey form a seat 8 upon which an exhaust nozzle (not shown) may bemounted.

I provide additional or by-pass exhaust steam passages 9 leading fromthe main exhaust steam passages 7 at a point abreast of the front end ofthe steam chamber and extending transversely and upwardly of the saddleand through the web plate 5 near the front of the latter and the outsideange of the web plate is projected forwardly as indicated at 10 toaccommodate the upper end of passage-way 9. This passage-way 9terminates 'in a flanged portion 11 having a seat 12 for mounting a pipe13 which is curved concentrically with the boiler shell and leads to afeed water heater 14 carried in the upper portion of the shell. Y

The steam passages 9 on opposite sides of the saddle preferably haveacommon dis charge outlet 15 and only a single pipe and pipe connectionis required for the feed water heater steam line and this connection islocated on the inside of the smoke-box, thus reciprocating water pump17.

projects outwardly fromthe upper wall 18 of the valve chambers 3 throughthe main exhaust passagefway 7 I provide a projection 19 at the junctionbetween passages 7 and 9 and this eliminates undesirable back ressure vin the main exhaust passage-way which would be present if thisprojection were not provided'or if some other corresponding device werenot used.

I also desire to simplify the complete locomotive structure by 'forminga bracket 16 integrally with thesaddle for the purpose ofmounting acombined steam cylinder and This vbracket the saddle structure whichextends between the right-hand steam chamber4 3 and the.vcorrespondingside of the. boiler supporting web'plate 5.

It will be understood that the location and formation of the elements ofmy novelsaddle structure `may be' varied fromthat shown I withoutdeparting from the spirit of'my in- 4 I cylinder mounting elements ofthe saddle and my invention also contemplates the use of a saddle splitalong the longitudinal center line of thelocomotive in accordance withthe wellknown practice in this art. As previously i stated,the saddleinvany of the forms referred to may be made integral with or separatefrom the framing members of the locomotive.

I contemplate the exclusive use of these and other modifications of myinvention which come within the scope of my claims.
